Abstract

The invention relates to an image acquisition method, device, equipment and medium of a magnetic resonance scanner. Wherein, the method includes: collecting vital sign data in real time; preprocessing the vital sign data; inputting the preprocessed vital sign data into a fully trained cyclic neural network; obtaining the fully trained cyclic neural network The output predicted vital sign data, wherein the predicted vital sign data is the vital sign data in the future preset time period predicted by the fully trained cyclic neural network according to the vital sign data; according to the predicted vital sign data data to control the MRI scanner for image acquisition. The present invention solves the problem in the related art that the image quality of gating triggering acquisition is easily deteriorated due to gating false triggering or missing triggering in the gating acquisition technology, and improves the acquired image quality.

Description

technical field [0001] The present invention relates to the field of medical equipment control, in particular to an image acquisition method, device, equipment and computer-readable storage medium of a magnetic resonance scanner. Background technique [0002] Magnetic resonance examination (Magnetic Resonance, referred to as MR) and positron emission tomography (PositronEmission Tomography, referred to as PET) / MR chest and abdomen scans are often limited by the influence of respiratory motion and heartbeat. Heart beating and breathing motion will cause a large loss of magnetic resonance signals and affect image quality. [0003] In order to reduce the influence of respiration and heartbeat on image quality, gated acquisition technologies are widely used in related technologies, for example, ECG-triggered gating, pulse-triggered gating, and respiration-triggered gating. The imaging technology of gated acquisition technology is used to monitor the vital sign signals of breath...
